Just wanted to know if Ultra is much better than Pro?
I am most concern about the Target voltages?
Pro: Wide target voltage range: 1.2V - 3.3V, 5V tolerant
Ultra: Wide target voltage range: 1.8V - 5.0V
Ultra is much faster though than the Pro but I am a bit worried that future boards would have a lower ref. voltages in turn will make this useless right? And currently I am using the imx53qsb which I believe has a 3.3v ref. so Ultra would be better. But would it be future proof?
Help me decide guys I need some inputs.
Thanks have a nice day.
